Research Interests

"There is a theory which states that if ever anyone discovers exactly how to quantize gravity, the universe will instantly disappear and be replaced by a universe in which quantizing gravity is even harder. There is another theory which states that this has already happened." (Paraphrased from "The Restaurant at the End of the Universe" by Douglas Adams.)

Barak's research involves one of the oldest and hardest unsolved problems in physics: the quest for a theory of quantum gravity, which is the unification of quantum mechanics and general relativity. Finding the correct theory of quantum gravity is crucial for a full understanding of many of the most fundamental concepts in physics such as black holes, the origin of the universe, and spacetime itself.

Specifically, Barak is currently working on one of the most promising candidates for a theory of quantum gravity, called loop quantum gravity. He is particularly interested in studying various aspects of the discrete quantum geometry of spacetime predicted by the theory.

In addition to research, Barak is also interested in science communication and outreach, in particular debunking myths and misconceptions.
